CoNTINUoUscUnRENT BLOWER on HAND] PUMP.

new and useful Continuous-Current Blower y or Hand Pump, of which the following is a specification. This invention of a continuous current blower or hand pump has for its object an easy and convenient air compressing and draft creating mechanism, which, unlike all now existing hand pumps, such as used for inflating tires, or in the form of lire-place bellows, etc., possesses the following distinc tive advantages:

1.-It gives a continuous current or stream of air, instead of an intermittentone. as is the c ase in all now existing hand pumps. .Q It is easily operated with one hand,

leaving the other hand free for attending to or adjusting other things.

3.-]t is compact and ornamental, with no piston rods or turning` cranks projecting and moving7 so that it can be carried around and used in public as a fan, and at home for rapid cooling, drying,"dusting, and in face massage. f

llt d'ffers also from thel air circulation starter, forming part' of my Pat. Appl.` Ser. #448,060, in the following new features:

1.-The large central body of said circulation starter with the cast on lflanges or rings enclosing its air inlets, is here', replaced by a small size central pipe, provided with four slots for air inlet ports and with a screwed on cap at each end for the compressed air discharge from either end, as may be desired. i v

2.--A separate flanged sleeve with: air in-y lets is` fastened to said central pipe. y

{L -The whole mechanism of the aspirator, instead of being operated openly,'like the Vcirculation starter, is here enclosed infa stationary cylindrical casing, fastened to' said central pipe and provided with longitudinal slots, throughwhich the movable cylinder is operated.` y s `Vly invention consists in the above set forth novel features, embodied in the com binations and constructions hereinafter set forth and claimed and as shown on the accompanying drawings, in which like charspecincatimi f Letters Patent.

acters designate the same parts in allv the views.

Fig. 1 is a sectional elevation of my continuous current aspirator.

Fig.v2 isfa side elevation of the same. Figs. 3-4-5 are cross sections of same; Figs. 6-7 are top and bottom views of same.

- corresponding Figs. 8%-9 are plan views of variousde-A q tails.

As seen onFig. 1, the aspirator consists of the central pipe 1, to which is soldered or welded on the sleeve 2, consisting of two anged hubs joined together by the four webs 5, as shown onFigs. 1'-38. To l'ix positively the position of the sleeve on the pipe, two pins 3 pass through the pipe and the hubs of the sleeve.

The open spaces between lthe webs 5 of the sleeve` communicate with the interior of the pipe 1 by the slots 11 in the pipe, as seen on Figs. 1 3. l

On either end of the sleeve 2 is a rubbe ring 6,"serving vras a shock absorber.

On the flanged hubs of the sleeve 2 are fitted the hollow piston 7 with its cover 8.

lThe bottom and the cover of this hollow piston are providedwith the air inlet openings 9, `whichare'closed oropened bythe rubberr flaps orrings 10 and 11 with the shields `12, both seated on the sleeve 2 inside the piston and clamped together between' the piston bottom and its cover 7`8;

Slidin'gly fitting the outer flange of thel immovably fastenedhollow piston is the movable cylinderl with its two covers 14, whose hubs slide alongl the pipe 1. f

Both covers 14 are provided with 'the air` inlet ports 15, closed or opened by the rubber iiaps or rings 1.6-17 withl the shields 18, which are providedfwith ferrules slidingly fitting v'the central pipe 1 and passing through thehubs of t-he covers y 14 and flanged over same, as shown on Fig. 1.'

Thesliding cylinder 13 is held up in its upwardposition by the spring 19 inside the upper part of the cylinder, one end of the spring pressing against the upper cover 14.,

The whole body of the aspirator is enclosed in theV stationary casing 20, consisting of a light polished sheet` metal cylinder, or of other suitable material, held in position by the two covers 21, fastened each to the central pipe 1 by 'the two nuts 22, screwed on to the pipe and secured against getting loose by the keys 23 and the'locking washers 24, shown on F igs. 1-9, in the followingV way: TheV key 23 passes through the pipe land notches in into the two washers 24: y

parting extra rigidity, aseXpla-ined herein-V after.Y

Both yendsof the central pipe 1 are provided with the screw caps 26 and 26, by which each end can be closed or opened. Provision is made, as shown, for attaching Y the Vcaps 26 to the covers 21 by a light hand chain (not shown von drawing).

The casing has two or more diametri-v cally opposite longitudinal slots 27 with the edges bent inward, as shown on Figs. 1-2, through which pass the finger grips 28 cast on to the outer surface of the movable cylinder 13. Y

The slits in the casingV 20 below the slots 27 (slitsnot shown on drawing) maybe left open, or can be soldered over, after the cylinder .13 with the fingerI grips 28 are in place.-

The'action'of the aspirator is as follows: Removing one or the other of the two caps 26, placing the thumb on the rigid washer plate and two fingers of the sameghand on the fingerV grips 28, and closing thumb and fingers together, the movable cylinder 13 is pushed down and the spring 19 inside is compressed. The rair inthe upper part of the cylinder becomes compressed; the valves 16 and 11 will-close the adjacent ports, while the valves 1() and 17 will fully open, .as is shown Aon Fig. 1, and the air from the upper part of the cylinder will be forced through the piston 7 intothe central pipe 1 and out at the o-ne of its ends from which the cap 2Ghas been removed. Y

Meantime the'lo'wer part of the cylinder 13 filled up with air, and when the thumb, and fingers are relaxed, the compressed spring 19 will-push the cylinder 13 back to its upward position; the air in its lower part becomes now compressed, the valves 17 and V10 will close the adjacent ports` the valves 11 and 16 will fully open, and theV air from the lower part of the cylinder will.

now be forced through the cover 8 into the central pipe 1 and out through the same open end.

Thus, a continuous stream of air is being discharged from the same end of the central o1 e.-

1 lin cooling, drying, dusting, etc., the air discharge through the further end of the central pipe, at 2G, will be convenient; while in face fanning and massaging the air discharge through the nearer end, at 26', will be more convenient.

The small openings 29 in the top cover 21 of the casing 20, shown on Figs. Y1-7., are air vents. A A
